GULF OF TEHUANTEPEC STORM WARNING: STRONG HIGH PRESSURE BUILDING
OVER THE WESTERN GULF OF MEXICO WILL SUPPORT STRONG GALES ACROSS
THE GULF OF TEHUANTEPEC THIS AFTERNOON, INCREASING TO STORM
FORCE GAP WINDS BY THIS EVENING. SEAS ARE ALREADY ROUGH TO VERY
ROUGH ACROSS THE GULF OF TEHUANTEPEC AND WELL DOWNSTREAM, BUT
WILL BUILD TO AT LEAST 23 FT BY WED MORNING, WITH A PLUME OF
ROUGH TO VERY ROUGH SEAS REACHING UP TO 500 NM TO THE SOUTH AND
SOUTHWEST OF THE GULF. LOOKING AHEAD, THESE WINDS AND SEAS WILL
DIMINISH SLIGHTLY THROUGH THU, BUT GAP WINDS TO GALE FORCE MAY
PERSIST INTO SAT NIGHT WITH ROUGH SEAS PERSISTING LONGER.
FOR THE FORECAST, STRONG HIGH PRESSURE BUILDING INTO NE MEXICO
WILL SUPPORT GALES ACROSS THE GULF OF TEHUANTEPEC EVOLVING INTO
STORM-FORCE GAP WINDS THIS EVENING. SEAS BY WED WILL INCREASE TO
23 FT OR HIGHER, WITH SEAS IN EXCESS OF 12 FT EXTENDING OVER 500
NM S AND SW OF THE GULF OF TEHUANTEPEC. AS THE HIGH PRESSURE
RESPONSIBLE FOR THE STORM-FORCE WINDS SLIDES TO THE EAST,
CONDITIONS WILL IMPROVE SLIGHTLY INTO THU. HOWEVER, GALE FORCE
WINDS WILL LIKELY PERSIST THROUGH SAT NIGHT. ROUGH SEAS MAY
PREVAIL THROUGH THE WEEKEND. TO THE NORTH, HIGH PRESSURE BUILDING
INTO THE SW UNITED STATES IS SUPPORTING GALES OVER THE NORTHERN
GULF OF CALIFORNIA THIS AFTERNOON. ALTHOUGH GALES WILL END BY
THIS EVENING AS THE HIGH WEAKENS SLIGHTLY, FRESH TO STRONG NW
WINDS WILL CONTINUE IN THE GULF THROUGH THE REST OF THE WEEK. IN
ADDITION, PLUMES OF STRONG NE GAP WINDS WILL FUNNEL ACROSS THE
BAJA CALIFORNIA PENINSULA AND INTO OFFSHORE PACIFIC WATERS MAINLY
N OF PUNTA EUGENIA THROUGH THE END OF THE WEEK.

SCATTERED MODERATE CONVECTION IS DEPICTED ALONG A SURFACE TROUGH
NEAR 135W FROM 22N TO 24N. THE TROUGH IS ASSOCIATED WITH A
LARGER MID TO UPPER LEVEL TROUGH THAT IS ALSO SUPPORTING A 1011
MB LOW PRESSURE FARTHER WEST NEAR 24N146W, WELL TO THE NORTHEAST
OF HAWAII. AN ARC OF FRESH TO STRONG SE WINDS IS CONVERGING
AROUND THE TROUGH AND TOWARD THE LOW PRESSURE, MAINLY NORTH OF
28N AND WEST OF 135W, AND FROM 22N TO 24N BETWEEN 134W AND 137W
PER LATEST ASCAT DATA. COMBINED SEAS ARE 8 TO 10 FT NORTH OF 20N
AND WEST OF 130W, IN PART DUE TO THE WINDS, BUT ALSO DUE TO
LONGER-PERIOD NW SWELL IN THE AREA. BROAD RIDGING DOMINATES THE
WATERS NORTH OF 15N AND EAST OF 130W. THIS PATTERN SUPPORTS A
LARGE AREA OF FRESH TO OCCASIONALLY STRONG TRADE WIND OVER THE
DEEP TROPICS FROM 06N TO 18N, BETWEEN 116W AND 135W, WITH 9 TO 11
FT SEAS IN A MIX OF WIND WAVES AND NW SWELL. THE NW SWELL IS
ALSO SUPPORTING 7 TO 9 FT SEAS OVER THE REMAINING AREA WEST OF
110W. FARTHER EAST, NE SWELL FROM THE GAP WIND EVENTS IN THE GULF
OF TEHUANTEPEC ARE REACHING WESTWARD TOWARD 105W ALONG ROUGHLY
10N. MODERATE WINDS AND SEAS ARE NOTED ELSEWHERE.
FOR THE FORECAST, THE FRESH TO STRONG SE WINDS BETWEEN THE
THE LOW PRESSURE NORTHEAST OF HAWAII AND THE RIDGE TO THE
NORTHEAST WILL CONTINUE TO AFFECT THE WATERS NORTH OF 20N AND
WEST OF 130W THROUGH THU. LARGE NW SWELL WILL CONTINUE TO
PROPAGATE INTO THE WATERS WEST OF 125W, AND MIX WITH SHORTER
PERIOD SEAS ASSOCIATED WITH THE TRADE WIND FLOW OVER THE DEEP
TROPICS. ALTOGETHER, EXPECT 8 TO 11 FT SEAS ACROSS MUCH OF THE
AREA WEST OF 125W THROUGH TONIGHT. THESE WAVE HEIGHTS WILL
SUBSIDE TO 8 TO 9 FT AND DIMINISH IN AREAL EXTENT MID TO LATE
WEEK. MODERATE WINDS AND SEAS WILL PERSIST ELSEWHERE. BY LATE
WEEK, FRESH TO STRONG NE-E WINDS AND MODERATE TO ROUGH SEAS WILL
REACH AS FAR WEST AS 100W ALONG ROUGHLY 10N FROM STORM-FORCE GAP
WINDS IN THE GULF OF TEHUANTEPEC.
